I've seen them for dogs, and some of the companies say they work for cats, but the collars are huge and the volt too high for a cat. Electronic cat fences were taken off the market for a while but I see they are back. They appear to have smaller collars and lower voltage. By the looks of it, the collar is small enough to be carried around by a cat and the system looks good, but I need more testimonials from real people who've used it.

I found some reviews online about Radio Fence, one of the top sellers of the PetSafe Premium Underground Cat Fences, and the buying experience was excellent, installation was easy, but no one commented on how their cats liked it and how it worked for their cats. So...what I'd like to know is, has anyone used this product on their cat and how well does it work for you and your cat? I'm thinking that this might be the way to go for Neo.

There are a few other options out there, so I'll keep you posted on what I find.
